In a population of 200 individuals,if PTC testers are 150 then calculate the frequency of recessive alleles
Answers
Recessive alleles
Explanation:
Hardy Weinberg Equilibrium gives a mathematical expression that sum of frequency of alleles(dominant and recessive) will always remain constant
p+q=1
where p= frequency of dominant alleles; q= frequency of recessive alleles
In the given question,
Total number of individuals=200
PTC testers(dominant)=150 (PTC-tasting ability is a simple genetic trait governed by a pair of alleles, dominant T for tasting and recessive t for non tasting)
Frequency of dominant allele will be=150/200=0.75
Frequency of recessive allele (non tasters) will be,
0.75+q=1 (using p+q=1)
q=1-0.75=0.25
Frequency of recessive alleles comes out to be 0.25
Explanation:
A recessive allele is a kind of genetic code that does not produce a phenotype if a predominant allele is present. In a predominant/latent connection within two alleles, the recessive allele’s results are concealed by the more exciting results of the dominant allele. An allele is a special variety of a gene or a particular section of DNA. Several alleles present slightly various proteins, which work in various ways. The passive allele generates a non-functional protein.
